Email Infrastructure Engineer

Workweek is reimagining how business leaders create, connect, and collaborate.

At Workweek, we’re solving what we call the knowledge expert paradox. It’s the idea that the more experienced a business leader becomes, the harder it is to access their knowledge.

We’re fixing that by building Operator Networks, professional communities where every member is a verified business leader in their field. These are spaces built for real conversations, content that’s actually helpful, and fun events. All for people who actually do the work.

Inside each community, members can connect with each other, swap ideas, talk shop, or create their own newsletters and podcasts. It’s how we’re reimagining what a social network can be: not built for attention, but for expertise.

Ultimately, we’re solving the paradox at scale by creating the tools, environment, and incentives for business leaders to share what they know. And we do it all for free.

We make money through our Partner Platform, a B2B ad platform that helps marketers invest, attribute, and scale their dollars more effectively. Think of it like if Facebook Business Manager was built for real B2B sales cycles.

About the role

We’re looking for an Email Infrastructure Engineer to architect and scale the system that powers newsletters across our Operator Networks. This is a foundational role where your work will make it seamless, fast, and reliable for members to create and send content every day.

You’ll build and manage the infrastructure that ensures Workweek’s newsletters are delivered at scale with best-in-class deliverability and performance. You’ll design, deploy, and tune MTAs, work closely with ESPs, and make sure our email stack integrates cleanly into our five networks, including into the feed, library, and our Partner Platform for advertisers.

This role reports to our Director of Engineering and works closely with product managers, designers, and engineers across multiple teams.

What you’ll do

• Architect, build, and maintain Workweek’s email delivery infrastructure powering our Operator Networks
• Design, deploy, and manage Mail Transfer Agents (MTAs) for high deliverability and reliability
• Optimize sender reputation, authentication (SPF, DKIM, DMARC), and engagement tracking
• Integrate with ESPs like Send Grid, Mailgun, or Marigold, and troubleshoot SMTP and routing issues
• Implement Site Reliability Engineering (SRE) best practices to ensure uptime and scalability
• Collaborate cross-functionally with product, data, and design teams to ensure clean integration with our platform and advertiser systems
• Document infrastructure and establish incident response and root cause analysis processes
• Partner with the Partner Platform team to enable reporting and advertiser reach across our email ecosystem
• Use AI tools like Claude to automate, document, or troubleshoot where it makes sense, embracing AI as a force multiplier rather than a replacement

Qualifications

• Deep expertise in email infrastructure, MTAs, and SMTP protocols
• Proven track record building and maintaining scalable email systems
• Hands‑on experience with deliverability optimization, anti‑spam measures, and IP reputation management
• Experience with ESPs like Mailgun, Send Grid, or Marigold
• Familiarity with cloud infrastructure and CI/CD systems
• Strong debugging, incident response, and documentation habits
• Collaborative mindset with the ability to work cross‑functionally
• AI‑curious and open to using tools like Claude to make your work faster, smarter, and more creative
• Bonus:
  Experience launching or scaling email infrastructure at a SaaS or platform company
• Competitive pay (we don’t pay based on location, we assign value to the role)
• Equity in Workweek
• Remote operations with the ability to work in the time zone of your choice (or work IRL in our Austin, TX office)
• Unlimited PTO with a minimum of 3 days/quarter used
• 100% health insurance coverage, 75% coverage for dependents, and $150/month towards an HSA (or $150/month health stipend if insurance not used)
